Last April we posted a story about Sarah Outen, an adventurous 26-year-old from the U.K. who had set out to circumnavigate the globe using nothing but her own power. Sarah called her journey the London2London expedition and over the past 12 months she has traveled by kayak and bike across Europe and Asia. Now she is preparing to embark on the next stage of her journey, a solo row across the Pacific Ocean.

Sarah is currently in Choshi, Japan, where she is busy making the final preparations to her 21-foot rowboat named Gulliver. That boat will be her home for the next seven months as she undertakes the physically and mentally demanding task of crossing the Pacific. If all goes as planned, and the weather is right, she’ll set out tomorrow on a 5179-mile row that will eventually end in Vancouver, Canada.

This isn’t Sarah’s first ocean crossing under her own power. Back in 2009 she rowed solo across the Indian Ocean as well. That expedition took more than four months to complete and covered approximately 3100 miles of open ocean. The Pacific will provide a similar experience, albeit on a much grander scale.

After setting out from London last year, Outen paddled down the Thames River and crossed the English Channel in a kayak. Arriving on the shores of France, she climbed aboard a bike and began peddling east, crossing through numerous countries in Europe and Asia along the way. She arrived in Japan last October, but the Pacific is unforgiving in the autumn and winter so she has waited until now to start this stage of the journey.

After she completes her row across the Pacific, Sarah will once again return to her bike and continue her round-the-world adventure. The next stage will involve riding across Canada and the U.S. Finally, she intends to cap the journey by rowing across the North Atlantic and back up the Thames River, finishing where she started under the London Bridge.
